Black screen after BIOS updates (HP Pavilion 15-cc665cl)

[Kid1685]

I am using HP Pavilion - 15-cc665cl. 

After BIOS updates in Windows 10 (x64), I got a black screen. I have tried almost all the suggested methods, such as:

- Press Windows + B + Power button,

- Remove battery, press the power button more than 1 minutes, and then plug in the Adapter

- Remove RAM, and then also the SSD

- Use a USB containing BIOS update file

- Combine all the above steps.

I have tried them several times and watched several HP videos, but it did not work.

After googling for similar problems, I found some information that my BIOS chip or main may be damaged and need to be replaced. I am quite scared now because It may be impossible or very costly to repair/replace the damaged ones. 

I hope that HP team can assist me with this problem.

Hello @Kid1685 

Sorry to hear that you are having problems ... I would like to help you.

Solution (1)

HP warranty valid -> Contact HP Support

Solution (2)

HP warranty expired

Service is required !
- The computer should be disassembled and checked.
- Thermal paste for CPU GPU and bridges must be renewed
- The function of the fan(s) must be checked

- Short circuit test 

- (if required) Bios (chip) desolder, reflash, Bios (chip) solder in

- Charger/battery test

- Components test

- General cleaning ...

You should have it <serviced> by a professional notebook (chip level) repair store.

Good luck

Thank for the help.

It seems very costly to have my HP serviced in Tokyo.

Thinking about buying a new one,

Hello @Kid1685 

See -> Maintenance and Service Guide

Remove (hard/SSD) drive(s) and RAM !

=> Sell notebook as a <spare part donor>.

The following parts are still valuable to sell:

- Cover/Housing

- Keyboard

- Touchpad

- Screen

- Webcam

- Wifi card

Good luck

Thank you for suggestion.

I will bring "him" back to my home country so that the unofficial  'specialist' there may save "him" with more afforadable price for me.

I will buy another one in Japan.

Sounds good...
